Trouble or fault
Possible cause
Action to be taken
Sawing wire vibrates
very strongly at a high
frequency.
Wire tension too high in rela-
tion to length of cut.
▶
Reduce tension on the
wire.
Wrong speed.
▶
Correct the speed.
Excessive sawing wire
wear.
Cutting speed, i.e. wire drive
speed, is too low.
▶
Increase drive speed or
cutting speed.
Inadequate cooling of the
diamond sawing wire.
▶
Ensure adequate cooling
of the diamond sawing
wire.
Cutting or contact length too
short.
▶
Increase the cutting or
contact length.
Wire tension too high in rela-
tion to length of cut.
▶
Reduce tension on the
wire.

Disposal
Most of the materials from which
Hilti
products are manufactured can be recycled. The
materials must be correctly separated before they can be recycled. In many countries,
your old tools, machines or appliances can be returned to
Hilti
for recycling. Ask
Hilti
Service or your Hilti sales representative for further information.
In accordance with the European Directive on waste electrical and electronic equipment
and its implementation in conformance with national law, electric tools, machines or
appliances that have reached the end of their life must be collected separately and
returned to an environmentally compatible recycling facility.
▶
Disposal of electric tools or appliances together with household waste is not
permissible.
Drilling and sawing slurry
Disposing of drilling and sawing slurry directly into rivers, lakes or the sewerage system
without suitable pretreatment is problematic from an environmental point of view.
▶
Ask the local public authorities for information about current regulations.
We recommend the following pretreatment:
▶
Collect the drilling or sawing slurry (for example, using a wet-type vacuum cleaner).
▶
Allow the drilling or sawing slurry to stand for some time or add a flocculation agent
to help the fine particles in the slurry settle and separate from the water.
▶
Dispose of this solid portion of the drilling or sawing slurry at a construction waste
disposal location.
▶
Neutralize the remaining water from the drilling or sawing slurry (alkaline, pH-value >
7) by adding an acidic neutralizing agent or dilute it by adding a large quantity of water
before allowing it to enter the sewerage system.
